BOTTLEFSTOPPE.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed September 19, 1904:. Serial No. 225,011.

To (ill whom it may concern:

Be it known that I, JOHN J. MULVANEY, a, citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

.The object of my invention is to produce a simple, cheap, and efficient bottle stopper or closure which can be removed from the bottle-mouth without the use of the bottle-openers or instruments or devices for removing the bottle stopper, closure, or cap as now used.

My stopper or'closure can be removed by simply exerting pressure, striking or forcing the bottle up against any permanent object, the pressure or force exerted against the stopper or cap denting it or forcing the metal inward, this operation forcing the annular lower crimped edge of thecap 0d of the mouth of the bottle. Thus the cap or stopper can be picked off or will fall of its own accord.

The stopper consists of a metal cap and a gasket made of cork. rubber, or equivalent material. This gasket is placed inside the cap and rests on the annular mouth of the bottle when in use.

In stoppers now in use the gasket and metal caps are practically flat and lie in juxtaposition. My cap is elevatedthat is. extends or protrudes materially up from the mouth of the bottleand is strengthened by ribs, projections, or ridges.

In the accompanying drawings, forming part of this specification, Figure 1 is a view in elevation of the bottle, partly broken away, with my bottle-stopper in place and on the bottle, the bottle mouth and stopper being partly broken awayto show the construction. Fig. 2 is a view in elevation of a bottle, partly broken away, with my stopper in place, the

mouth of the bottle and part of the stopper beingpartly broken away to show the construction, the cap being bent in or dented,- the sides of the stopper being loosened up ready to drop off, theforce of the blow on the stopper having loosened up thecap. Fig. 3- is a top view lookingdown on the bottle and stopper in place; and Fig. 4 is a top or plan view of a stopper after my invention, instead of annular ridges being present in the caps curved or irregular'ridges being used.

1%; represents the bottle, and B the bottlenec C represents the metal cap, and D the gasket of the stopper or closure. This cap ,C is

- of peculiar shape'that is, elevated, semicircular, or of pyramid shapeiandextendsup materially from the bottle-mouth, leaving a space between it and the gasket D. The cap C is provided with ridges, ribs, or projections E to strengthen the cap. I may provide as many of these ridgesas desired.

These ribs are usually annular 0r surround the cap; but I may make them short, running from the center to the'edge of' the cap, as

shown in Fig. 4. I may dispense with them At its lower edge F the entirely,-if I desire. cap is corrugated, as shown.

The gasket D consists of a disk or annular piece made of cork, rubber, or equivalent ma terial. It is about the size of the mouth of the bottle, so that when in place it fits over the entire bottle-mouth. It may be madeof any other shape, it desired, and be'made of any material and may be fastened in the metal cap C in any desiredmanner. Instead of being flat, as shown. it may be made semicircular or elevated, as is the cap itself.

At its mouth the bottle A is provided with an annular flange or ring G. The corrugated lower part Fof the metal cap G fits over this ring or flange G and is crimped around it. Thus the stopper is held in place. the stopper is put on the bottle with some force, so that the gasket D fits tightly against the bottle-mouth, making an air-tight joint,

the crimping being done'to hold the stopper in this desired position. When it is' desired to open the bottle, a blow or force of any kind is exerted on the cap of the stopper. This of course bonds or dents in the cap, the force of the blow or exertion being transmitted to the edge of the cap, where it rests with the gasket edge on the top of the mouth of the bottle, and being weakest from this point down to its crimped edge the blow exerted forces the crimps to relax their hold, as shown in Fig. 2, and the stopper can be removed from the bottle with the hand, or it drops ofi'. It will be readily seen that by the use of my invention bottle eork pullers, bottle-openers, either hand or machine, are dispensed with.

My improved b ttle-stopper can be used on all kinds of bott es and may be connected thereto in any'desired manner, the main feature being the elevated, pyramid, cone-shaped, or beehive arch-cap, which extendsup materially from the bottle-mouth, so as to receive a blow endcenvey the force of the impact to the erimped edge and foree its hold 03 of the bottle-mouth. I

What 1 claim as new and of my invention, and desire to secure by Letters Patent, i.s

I. In e bottle-stopper, e metei eep said cap extending up meterialiy ebove the bottlemouth, e space being provided between the top of the bottle and the under sideof the cap, in combination with e gasket interposed between said cap end'the mouth of the bottle and means for hoiding seid cap and gasket on the Dottie, as set forth, and for the purposes specified 2. in e bottle-steepe?" emetsji eep, said cap extendihg up materially ebet'e the bottlemouth, 2. space being provided between the top of the bottle and the under side of the cap,- strengtheningwibs formed in said esp, in combination with e gasket interposed between subset! said cap and the mouth of'the bottle, and means for holding said cap and gasket on the bottle, es set forth and for the purposes set forth.

3. in e bottle-stopper, a metal cap, extending up materially above the bottle-mouth, so that a space is provided between the top of the bottle and the under side of the cap, an interposed gasket between the cap and the bottle-mouth, the metal cap being crimped on the bottle-mouth as and for the purposes set forth.

4:. in a bottle-stopper, a. metal cap, said cap extending up meterieliy above the bottlemouth, so thetespece is left between the bottie-mouth end the under side of the cap, and means for holding said cap on the bottlem'outh, es and for the purposes set forth.
